destinyland writes: California scientists have just created a new biofuel using plants that burns just as well as a petroleum-based fuel. "The discovery, published in the journal Nature, means corn, sugar cane, grasses and other fast-growing plants or trees, like eucalyptus, could be used to make the propellant, replacing oil," writes the San Francisco Chronicle, and the researchers predict mass marketing of their product within 5 to 10 years. They created their fuel using a fermentation process that was first discovered in 1914, but which was then discontinued in 1965 when petroleum became the dominant source of fuel. The new fuel actually contains more energy per gallon than is currently contained in ethanol, and its potency can even be adjusted for summer or winter driving.
